Two incumbents face off against three challengers in Denver City Council at-large race.

Denver’s two incumbent atlarge City Council members — who represent the entire city — hope voters now clutching their mail ballots will give them another term based on their leadership and experience.

But three challengers, aiming to tap into frustrations on a variety of fronts, argue the council needs more robust advocates than Robin Kniech and Debbie Ortega.

They point to a city grappling with a whiplash-inducing pace of development, skyrocketing housing costs and costly settlements in jail and police-abuse cases. And they say the council’s ideas, especially from the at-large members who aren’t tethered to a district, have fallen short.

Kniech and Ortega are finishing their first terms as at-large members. Hoping to out-poll one or both are Kayvan Khalatbari, Jose Silva and Jeffery Washington.

The at-large race typically is overshadowed by the mayoral contest, as in 2011, or by active district races, as has happened this year, political analyst Eric Sondermann said.

That means at-large incumbents usually have a big advantage, barring widespread unrest among voters for challengers to channel.

“At-large races are even more about name ID and citywide concerns and citywide narratives, as opposed to a specific development, a specific park, a specific bunch of potholes or flower beds,” Sondermann said.

Voters get two picks. Unlike in other races, there’s no runoff if nobody clears 50 percent. Four years ago, in a five-way race, Ortega led with 33 percent of the votes. Kniech notched 22 percent.
